Usage

General Description

4-(N,N-dimethylamino)benzeneazo-2-naphthalene, also known as Oil Red O, is a lipophilic, azo dye commonly used to stain lipid droplets in various biological samples. It is a red powder that is soluble in organic solvents and has a strong affinity for lipids, making it a valuable tool for visualizing lipid-rich structures in cells and tissues. Oil Red O stains lipid droplets by binding to their hydrophobic surfaces, allowing for easy visualization under a microscope. Due to its specificity for lipids, Oil Red O is widely used in research to study lipid metabolism and accumulation in various biological samples, including adipocytes, liver tissue, and other lipid-rich organs. Additionally, it has also been used as a histological stain for the identification of neutral lipids in biological samples.
